Poison Dart Frog - Enough Poison To Kill More Than 10 Men

Poison dart frogs have been given this name because their poisonous secretions have been used by Amerindian tribes to poison the tips of blowdarts. Only three species are dangerous to humans. The most poisonous of these frogs is the Golden Poison Frog – it has enough poison on average to kill more than ten grown men or about ten thousand mice. Unlike most frogs, these species are active during the day and frequently display brightly-colored bodies.

The beautifully brilliant colors (which can be yellow, gold, copper, red, green, blue, or black) and complex patterns of these frogs are a warning to possible predators that they don't make good eating - a tactic called aposematic coloration. There could be more than 175 species in this family of amphibians, all native to Central and South America. Many species of poison dart frogs are classified as critically endangered.
